Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488812, here are decompositions:

  • 19 + 2147488793 = 2147488812
  • 61 + 2147488751 = 2147488812
  • 71 + 2147488741 = 2147488812
  • 193 + 2147488619 = 2147488812
  • 199 + 2147488613 = 2147488812
  • 233 + 2147488579 = 2147488812
  • 239 + 2147488573 = 2147488812
  • 269 + 2147488543 = 2147488812

Showing the first eight; more decompositions exist.
